BRAKE-BLOCK.

SPECIFICATION forming part of Letters Patent No. 701,220, dated May 27,1902.

Application filed December 28,1901. Serial No. 87,616. (No model.)

To all whom, it may concern.-

Be it known that 1, JOHN S. ODGERS, of Gentral City, in the county ofGilpin and State of Colorado, have inventedanew and useful Improvementin Brake-Blocks, of which the following is a specification.

My invention is designed to furnish an improved brake-block for buggies,wagons, and all wheeled vehicles which shall provide a stiff and rigidconnection for the rub-iron to the operating-bar that carries it, sothat the brake-shoe will not become loose and tilt on its point ofsupport, and yet provide a construction which will permit the positionof the brake-shoe and rub-iron to be adjusted to the plane of the wheel,whose dish is sometimes changed in adjusting new tires to the wheel andit consists in the special construction and arrangement of the shoe inrelation to the supporting-bar, as will be hereinafter fully describedwith reference to the drawings, in which+- V Figure 1 is a perspectiveview of the brakeshoe and supporting-bar connected together. Fig. 2 is aperspective view of the brake-shoe alone, and Fig. 3 is a side view ofthe brakeblock complete as applied to the wheel.

In the drawings, A represents the supporting member.

B is the brake-shoe, and O the rubiron carried by the brake-shoe andarranged to bear against the circumference of the wheel. The brake-shoehas two parallel side flanges 5 73 (see Fig. 2,) between which therub-iron O is secured by bolts or rivets passing through holes 7) b inthe back of the brake-shoe. The back of the brake-shoe is also formedwith a transverse ridge Zr and on each side of it has a square hole band I). These holes are arranged in vertical alinement and both are inthe same vertical plane with the wheel.

The supporting member A is made with a concave part c which connectswith a suitable cross-bar connected to the running-gear of the vehicleand capable of being advanced toward the wheel in the usual way. Themetal end portion of this supporting member is formed with wings a a,which lie fiat against the back of the brake-shoe, and has two elongatedslots at (1 arranged transversely to the brake-shoe. When the supportingmember A is applied to the brake-shoe, the concave side of the archedportion a fits snugly against and over the transverse ridge b of thebrakeshoe, and a bolt or rivet D is passed through the slot at on eachside and also through one of the square holes I) in the brake-shoe toconnect them firmly together. The heads of the bolts D are countersunkin the brakeshoe and may be secured on the outer side of the wings aby'jam-nuts; but for the sake of a rigid connection and to preventcoming loose from vibration a riveted head is preferably employed, asshown. The vertical alinement of the bolt-holes b b and bolts D D bracesthe shoe and prevents it from rocking loose about the horizontal axis ofthe supporting-bar A. The square holes I) in the brake-shoe prevent thebolts from turning, and the ridge b entering the groove of the part amakes a tight fit and prevents moving in any way. If, however, inputting on new tires for the Wheel its dish and theplane of the tire arechanged, as sometimes occurs, the shoe B may be loosened slightly fromthe part A and the bolts D slid in the slots a and retightened, so as tobring the rub-iron into the plane of the wheel again.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A brake-block comprising a shoe having a transverse ridge across itsback and abolthole on each side of the same, one above and the otherbelow the ridge, and both lying in the plane of the shoe and in avertical line with each other, and a supporting-bar having a horizontalgroove on its face to receive the transverse ridge of the shoe andhaving also formed on it two slotted wings, and one above and the otherbelow the bar, and bolts passing through the slots of the wings and thevertically-aline'd holes of the shoe substantially as and for thepurpose described.

2. A brake-block comprising a shoe having parallel side flanges b b anda back portion formed with a transverse ridge with pairs of bolt-holesZ) Z), one pair above and the other below said ridge and both lying inthe vertical shoe substantially as and for the purpose deplane, and asupporting-bar having an arched scribed; portion a fitting on the ridgeand formed also with rigid slotted wings a, a, one above and JOHNODGERS' 5 the other below the arched portion, and bolts Witnesses:

D D passing through the slots of the wings THOMAS CODY, and thevertically-aimed holes of the brake- MORRIS HAZARD.
